WINDMILL-QOUPLING.

SPECIFICATION forming part of Letters Patent No. 590,997, dated October5, 1897. Application filed November 28, 1896. Serial No. 613,096. (Nomodel.)

1'0 all whom it may concern:

Be it known that 1, ANDREW Y. ll/IASSER, a citizen of the United States,residing at the city of Three Rivers, in the county of St. Jo-

seph and State of Michigan, have invented a certain new and usefulWindmill-Coupling, of which the following is a specification.

My invention relates to improvements in windmill-couplings.

This device is to take the place of the oldfashioned pin, which is soliable to become lost in use and which requires heavy labor and care toproperly insert, the operation requiring time and patience.

The objects of this invention are to provide a simple coupling which canbe easily and quickly operated; also, to provide a coupling in which allrattling and shucking of the parts is prevented. Further objects willappear definitely in the detailed description. I accom plish theseobjects of my invention by the devices and means described in thefollowing specification and illustrated in the accompanying drawings, inwhich-- Figure l is a front elevation of my improved coupling, parts ofthe pump-rod and windmill pump-rod being broken away. Fig. 2 is avertical sectional view showing the coupler in the coupled position,taken on line 2 2 of Fig. 1. Fig. 3 is a view, partially in section, onthe same line, showing the coupler uncoupled.

Similar letters of reference refer to similar parts throughout theseveral Views.

Referring to the lettered parts of the drawings, A represents thewindmill pump-rod.

A is the metal slide on the end of the same.

A is the piston-rod of the pump. The piston-rod A" fits into a suitableguideway or slideway into the slide portion A of the windmill pump-rod.I

Secured to the back side of the slide A is a spring-rod B, whichterminates at the bottom in a lateral stud B, which serves as a pin forcoupling the windmill pump-rod and the piston-rod of the pump. The upperpart of the spring-rod B is formed into an eye, and is secured to theslide-casting by the bolt B". Ears G extend out on the back of thisslide A. Supported between these ears G is a cam 0, having a suitablelever with stops. One

and is uncoupled, as shown in Fig. 3, the operator turns down the leverwhich operates the cam O and presses the rod B into the slot at theback, forcing the stud B out against the piston-rod A of the pn mp. Whenthe parts move opposite each other, the elasticity of the rod B pushesthe stud B into the hole in the piston-rod and couples the two together.WVhen the two are coupled together, the elasticity of the rod B clampsthe piston-rod A tight against the opposite side of the slide A andprevents any rattling of the same, and the parts fit comparatively closeas a protection against shucking and jerking. It will be observed inthis connection that when the coupling is not complete at the start andit is necessary for the stud B to slide upon the rod A there is atendency to start the rodand save it from a violent jerk at the couplingof the parts.

- When it is desired to uncouple the windmill from the pump, the leverand cam O are thrown upward from the position indicated in Fig. 2 tothat shownin Fig. 3, but the elasticity of the rod B Withdraws the studB into the position indicated in Fig. 3 and the pump is uncoupled fromthe windmill.

It-will be observed from this description that the device is exceedinglysimple, being a spring-rod and a lever-cam 0 added to the devicesalready in common use. The old parts are slightly varied to accommodatethe cam and spring. I desire to state in this connection that thisstructure can be somewhat varied without departing from my invention. Adifferent style of spring might be substituted instead of the spring B,and while it is exceedingly desirable to have all the parts constructedin as few pieces as possible I am aware'that the structure could be madein more pieces in a satisfactory manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is I 1. In a windmill-coupling device thecombination of a windmill pump-rod A, the slide A, thereon With a slot13" through the back thereof a spring-rod 13, secured to the back ofsaid slide, a laterally-projecting stud B, adapted to couple with thepump-rod, and a cam O, eccentric on one side and fiat on the othersupported between ears 0, to actuate the spring-rod B; and the pump-rodA, with a suitable hole to be engaged by stud B, all coactingsubstantially as described for the purpose specified.

2. In awindmill-coupling device the combination of the slide A, thespring B, secured thereto bearing the stud B, cam C, With its sideflattened to act upon the spring B, at a distance from the coupling-studand the piston-rod of the pump A, containing a hole to be engaged by thestud B, as specified.

I11 a windmill-coupling the combination of the slide; the piston-rod ofthe pump; a spring secured to said slide with a stud to engage thepiston-rod of the pump, a cam on said slide positioned to act on saidspring and force the stud into engagement with the piston-rod asspecified.

In Witness whereof I have hereunto set my hand and seal, in the presenceof two Witnesses, this 5th day of November, 1896.
